SPIRAL THUMB-TACK.

., Specification of Letters Patent.

Patented July 4, 1916.

Application filed December 13, 1915. Serial No. 63,618.

manufacture and in 'particular to a spiral thumb tack.

It is an object of this invention-to construct a tack which has theappearance of a normal thumb tack and which serves to supportphotographs, pictures, cards, and

the like. The tack consists of a head made 7 of metal'plate, to which alength of spring wire is attached in any suitable manner and which,after a suitable number of coils, ends in a sharpened point.

'In' the accompanying drawings which form a part of this specification,I have shown an embodiment of my invention and in which:

Figure 1 shows the improved thumb tack attached to a wall, or the like,and a card or photograph held by said tack. Fig. 2 is a front elevationof thetack. Fig. 3 is a perspective view thereof, looking from the lowerside. Fig. 4 is a vertical cross-section through the center thereof.Fig. 5 is a plan view of the under side thereof.

The improved tack is made of. a circular head 10 made of thin metalplate. The same is preferably slightly convex on its upper face. Alength of spring wire 11 is suitably attached by soldering or any otherconvenient method to the under-face of said head. The length of wire 11is bent to form two circular coils 12 of a size corresponding-to theperiphery of the head, or slightly smaller, so that said coils will'notbe visible when the tack is viewed from the top.

' It is obvious that the number of coils is immaterial, and, if desired,more than two Copter! of this patent may be obtained for coils may beformed, but ordinarily two coils are sufficient for the purpose forwhich the tack is intended. These coils are in close relation to eachother, so that a photograph or card, and the like, when inserted betweenthe coils, as shown in Fig. 1, will be se curely held in position by thefrictional contact of the wire. The lower coil is bent so that the endportion 13 extends to the center of the coil, from which a verticalsharpened portion 14 extends downwardly to form the end.

From the foregoing descriptiomthe use of the tack will. be obvious. Thetack is fastened to any suitable object, such as a wall, or the like, bypressing on the head, which will force the sharpened end into the wall.A card, or the like, may be inserted between the coils, where the samewill be held securely in position by the frictional contact of thelatter.

It is thus seen that I have devised an improved thumb tack consisting oftwo parts,t"he head and the length of wire,

which, when viewed from the top, has the appearance of a normal thumbtack and may be used as such, but which serves to frictionally suspendphotographs, cards, and

1 the like.

said Wire being bent toward the center of the last coil and projectingdownwardly therefrom to form a sharpened point.

In testimony whereof I have signed name to this specification.
